The low female singing voice in opera, choir, and non, classical music (the alto part in choir is sung by contraltos and mezzo-sopranos with strong low notes). The contralto has a range from F3 (below middle C) to G5 (the second G over middle C). This deep, dark female voice is the rarest female voice and they are known to sound almost like men on their lowest notes.

Sitting between mezzo sopranos and tenors, contraltos have relatively few roles in opera as little has been written specifically for them and what roles they have are usually that of maidservants, mothers, grandmothers, and friends of the heroine, but they occasionally get hardy roles, notably witches and goddesses. They also play roles originally meant for castratos (when mezzo-sopranos, countertenors, tenors, and baritones don't take them).

The lowest womyn's singing voice; at the bottom of their range, they sound almost like men, often leading to people mistaking them for men on the radio, telephone, or wherever.

The alto range, which is below soprano, is really an easy combination of the mezzo-soprano range and the contralto range; the mezzo-soprano is the medium female voice and therefore the higher of the two.

The contralto voice is a pretty rare voice. And there is little work that was written specifically for the contralto. Countertenors, mezzo-sopranos, and often tenors, baritones, and basses take the roles that were written for them.

Marian Anderson and Kathleen Ferrier were legendary operatic contraltos in their day.

The lowest female singing voice. At their lowest, contraltos sometimes sound like Barry White. There are traditionally very few roles for contraltos in operas, though modern musical theatre has begun to include them. A common saying is that contraltos are only allowed to play "witches, bitches and britches," with "britches" referring to a trouser role.

The lowest womon's singing voice; on her lowest notes, she sounds almost like a man, often leading to people mistaking them for men on the radio, telephone, or wherever.

The alto range, which is below soprano, is really a mish-mash of the mezzo-soprano range and the contralto range; the mezzo-soprano is the higher of the two.

The contralto voice is pretty rare since there is little work that was written specifically for them. Countertenors, mezzo-sopranos, and often tenors, baritones, and basses take the roles that were written for them.
